Vinayakumar B resolved HDFS-7099. --------------------------------- Resolution: Duplicate Same discussion going on in HDFS-6633. So duplicating it. > Support polling for more data from a write-in-progress file using same > DFSInputStream > ------------------------------------------------------------------------------------- > > Key: HDFS-7099 > URL: https://issues.apache.org/jira/browse/HDFS-7099 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: Vinayakumar B > Assignee: Vinayakumar B > > Currently DFSInputStream can read only till the bytes written which were > written by the time of Opening it for reading. > But, later there can be more bytes written to same file. > If client expects more data to be available, then client can poll it > continuously for more data without re-opening the stream. > One simple example use case for this is tailing logs files. > Currently LocalFileSystem supports this. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
